“We are a rock band, pure and simple,” says gravelly-voiced lead singer Brent Best, but as this third release from the Texas-based outfit makes clear it isn’t so simple after all. The group have staked out a rather original space somewhere between country and punk rock, and they’ve filled it with quirky characters, memorable stories, and high-octane music that refuses to be pinned down and categorized. The instrumentation ranges from fiddle and mandolin to accordion and tuba; the sound is sometimes folk-country delicate, sometimes frenzied hard rock, though it leans more to the latter than the former. As for the lyrics, Slobberbone’s ideas occasionally run out before a track ends, but they’re generally dark and/or funny, and more than a little twisted.
